Corrections and clarifications

• Thomas Jefferson was not an author of the US constitution, as an article claimed (US first amendment not O'Donnell's cup of tea, 20 October, page 19). Jefferson, the main author of the Declaration of Independence of 1776, was abroad serving as minister to France when the constitution was written in 1787.

• A photograph purporting to show the transport secretary, Philip Hammond, was in fact of the health secretary, Andrew Lansley, and vice versa, in a graphic included in our coverage of the comprehensive spending review (Who's smiling … and who isn't, 21 October, pages 4-5).

• An article about the popularity of a collagen drink in China was accompanied by a photograph showing an advertisement written in Japanese (Drink those wrinkles away …, 18 October, page 3, G2).

• Yesterday's cryptic crossword by Bonxie (No 25,136, page 41) was an inadvertent reprint of a puzzle that appeared earlier this month. We should have printed No 25,147, which appears correctly at guardian.co.uk/crossword and is also available from the address below.
